Title: Optical receiver
Inventor: FURUTO YOICHI
IPC: H04B10/077
Filed: 1994-03-11
Abstract: PURPOSE:To cut off a clock signal when there is no optical input signal by providing a comparator for receiving the output voltage of a level comparator and the oscillated signal of a voltage controlled osicllator(VCO), for comparing both of them and for outputting the result as the clock signal. CONSTITUTION:The oscillation frequency of a VCO 6 is fixed at the frequency of an output from an amplification factor variable amplifier by a frequency locked loop composed of a phase frequency detector 7, loop filter 8 and VCO 6. Further, the phase frequency detector 7 compares the oscillated signal of the VCO 6 with the output of the amplification factor variable amplifier 3, identifies them, reproduces them and outputs the result to the outside as a data signal. On the other hand, the oscillated signal of the VCO 6 is outputted through a comparator 10 as the clock signal. Namely, the detected output is converted to a desired DC voltage, compared with the oscillated signal of the VCO 6 by the comparator 10 installed at the output prestage of the clock signal and outputted and when the optical input signal is eliminated, the clock signal is cut off.
